What are your thoughts on the EPA’s Residential Light Fixture “Technical Amendment,” and their attempts to remove a “competitive disadvantage” for legacy technologies?
While researching for this month’s Industry Focus on Automotive Electronics, I encountered an issue pertaining to infotainment I never considered: government regulation. It arose as the I was asking questions about head-up display (HUD) technology. Industry trends are showing that caller ID, lights for speed, gas and warnings, radio station name...
When consumers shop for a new vehicle, they look at price and gas mileage as key factors in their purchasing decision. Technology, now more portable than ever, is also on the mind of the American consumer. Cell phones, GPS navigation devices, mp3 players, and other video applications are becoming both a necessity and a convenience for drivers.
In this paper we present two unique NVM solutions which can close two significant gaps in the embedded memory IC world. Today’s designers have a large choice of embedded non-volatile memories (NVM) verified in different production technologies. These memories can be divided into three groups
Protecting Ethernet interfaces from cable discharges can create a challenge for engineers because good protection must meet two criteria. First, and most important, a protective device must effectively clamp a transient to a safe voltage. Second, the device must present an acceptable capacitive load on high-speed differential transmission lines. Good planning and careful selection of transient voltage-suppression devices can adequately protect Ethernet interfaces from electrostatic discharges (ESDs) and cable discharge events.
When engineers start to evaluate a precision digital multimeter (DMM) they first think about resolution and accuracy. "They may start with requirements for a high and low measurement limit and a tolerance," said Chuck Cimino, a marketing director at Keithley. "Then they figure out how many digits they need without going into a lot of the DMM's detailed specs."
Previously analog-to-digital converters (ADC) at high input frequencies were limited in usefulness due to distortion and noise performance. Today, however, ADCs can provide nearly 9.5 bits of effective number of bits (ENOB) at radio frequencies (RF) of 1 GHz with signal bandwidths greater than 200MHz. Such performance at high frequencies eliminates a mixer stage, simplifying receiver design to improve overall system performance.
When engineers tackle a project that uses ZigBee communications they may get a surprise. Unlike point-to-point communications, ZigBee involves a network that can establish nodes, repeaters and complex mesh topologies. The proper test tools--often called "sniffers"--help engineers diagnose ZigBee-network problems that could otherwise turn into nightmares.
On June 2, 2008, the Environmental Protection Agency (last seen as the supervillains in “The Simpsons” movie) released a “technical amendment,” version 4.2, to the Energy Star residential light fixture specification. Remember when Nintendo introduced the ubiquitous “Seal of Quality?” The great crash of 1983 was caused by a number of factors, not the least of which was lousy software...
The recent cries over shoddy manufacturing performance have put electronic product designers in a tough spot – and frankly, left them baffled. Time after time, their design concepts that had the makings of a sure bet evolved into a product with deficiencies reported from thousands of customers – leaving many unanswered questions.
Networks Take High Performance Motion Control to the Next Level Networks simplify software development, axis coordination, code updates, and system characteristics.
What are the most important factors to consider when developing a new product?
Power has the essential role in the operation of a factory since no machinery can run without it, but power isn’t a guarantee. Companies performing industrial automation lose up to millions of dollars and hours of production time annually due to power anomalies. There are two types of power anomalies: natural phenomena which are harder to control and internal anomalies which are easier to control.
“Can you stand another ZigBee presentation?” was the greeting I received from one of the many exhibitors I met at the 2008 Sensors Expo in Rosemont, IL. Indeed, wireless industrial networking devices were in abundance at this year’s show, along with what seemed like an increasing amount of companies presenting MEMS-based devices.
Many designs require a small amount of high-speed, instant-on programmable logic. These designs drive the thriving market for Complex Programmable Logic Devices (CPLDs). This article examines the definition of CPLDs, their applications, design methodologies and which factors to consider when selecting a CPLD.
